Amazon has been experiencing an outage for Seller Central, today, 19 June 2017.

Sellers are reporting intermittent outages with seller tools such as the forums and FBA fee calculator, while the Seller Central platform seems to be completely down with sellers receiving the following messages:

Amazon Seller Central: Seller Central is Temporarily Unavailable, We apologize for the inconvenience. Our technical staff is working on a solution.Amazon Seller Central: Internal Error – The website is having a technical problem, please try again.

While Amazon’s AWS is showing no outages, Amazon still does not seem to have publically acknowledged the outage.

SegWit is a movement among bitcoin miners to increase the block size from 1 MB to 2 MB (Megabytes). SegWit can be activated by the bitcoin miners collectively by the highest ratio of miners “voting” for it.

In addition to raising the blocksize, SegWit will also enable platforms to be built on top of the bitcoin network, giving it some of the malleability of the Ethereum network. The Bitcoin Lightning Network seeks to make transactions faster and more scalable on the blockchain, but will require SegWit to be activated by the miners. 95% of the miners must ‘signal’ their vote for Segwit in order to activate it. As it stands, many miners are not signaling for SegWit activation – perhaps due to the change SegWit could bring to the ecosystem or due to the potential loss of profit from easier transaction transfers (and lower transaction fees).

UASF / BIP 148 is a blockchain user movement to change the bitcoin core code to deny blocks not signaling for SegWit. If all goes well, 100 block confirmations after BIP 148 implementation, SegWit will be force-activated on the bitcoin network. The force activation take place by bitcoin nodes and users signaling their support for BIP 148 and rejecting mined bitcoins without SegWit support. By activating via the nodes of the blockchain network (rather than the miners themselves activating it) the benefits of SegWit are brought to the blockchain without the need for 95% of miner support. Blockchain miners can also force this upgrade with 51% signaling support for BIP 148.

The problem: Before that 100th block is confirmed on the blockchain, there is a potential for the blockchain to diverge into two. With transactions and mining taking place separately on each blockchain two coins will be born out of one, akin to ethereum and ethereum classic.

You’re trying to sell a Standard EC2 Reserved Instance with No Available Zone Scope

Per Amazon’s Requirements: Standard EC2 Reserved Instances can only be listed in the Reserved Instance Marketplace, if they are purchased with an Availability Zone scope. Since capacity is not reserved with regional RIs, they cannot be sold on the Marketplace at this time.

If you’re a registered seller and you are still receiving this error, you may be stuck with this particular reserved instance.

Some notes about selling reserved instances:

Reserved instances can be sold after they have been active for at least 30 days and once AWS has received the upfront payment (if applicable).

There must be at least one month remaining in the term of the Reserved Instance you are listing.

You must have a US bank account to sell Reserved Instances on the Reserved Instance Marketplace. Support for non-US bank accounts will be coming soon.

You will retain the pricing and capacity benefit of your reservation until it’s sold and the transaction is complete.

Your company name (and address upon request) will be shared with the buyer for tax purposes.

A seller can set only the upfront price for a Reserved instance. The usage price and other configuration (e.g., instance type, Availability Zone, platform) will remain the same as when the Reserved instance was initially purchased.

The term length for a Reserved instance will be rounded down to the nearest month. For example, a reservation with 9 months and 15 days remaining will appear as 9 months on the Reserved Instance Marketplace.

You can sell up to $50,000 in Reserved instances per year. If you need to sell more Reserved instances, complete the form found here.

Reserved instances in the GovCloud region cannot be sold on the Reserved Instance Marketplace.

Reserved instances purchased as part of a tiering discount cannot be sold in the Reserved Instance Marketplace.
